Image classification model training method and device, electronic equipment and storage medium

The invention discloses an image classification model training method and device, electronic equipment and a storage medium, and relates to the technical field of image processing, in particular to the technical field of image classification. According to the specific implementation scheme, gradient information of a loss function on a first weight of an initial image classification model is determined according to label information of an adversarial sample and the initial image classification model; adding disturbance information to the first weight of the initial image classification model to obtain a second weight; determining the back propagation gradient information of the loss function on the second weight according to the adversarial sample and the label information of the initial image classification model; and updating the first weight of the initial image classification model according to the gradient information and the back propagation gradient information to obtain a target image classification mo
